Meeting Results

Planning:
Mark has sent out a request for use-cases combined with request for participation in the work. As result of this we have already received a couple of intersted parties.

Mark, Scott and Nicola will all be in Mexico City and UCM will meet to discuss the use-cases on Thursday April 10. A call for use-cases has been set with deadline the 9th. This will also be broadcasted on the opening plenary.

Gunther presented his document on combined metamodel.

Gunthers proposals contain both parts of a set-based and a tree-based approached. A question that was raised whether it was fortunate to combine both approaches in one model. This is something that needs to be identified pluses and minuses.

The tree-based approach is the most common way to classify in the industry today. Gunther means that the tree-based approach will be to complicated in pracitcal use.
